Description

Technical Field

[0001] The present invention relates to the technical field of hospital building structures, and in particular to an assembled barrier-free passage and a construction method thereof. Background Art

[0002] As a key facility in medical buildings to ensure the safe passage of people with mobility impairments (such as wheelchair users, elderly patients, and people with physical disabilities), the core function of barrier-free passages is to eliminate height obstacles such as steps and steep steps through slope control, anti-slip treatment, and auxiliary support designs, ensuring that users can independently complete barrier-free passage through building entrances and exits and internal traffic lines.

[0003] However, traditional channels have significant limitations in planning, construction and functional expansion, as shown in the following aspects:

[0004] (1) Solidified construction method: Currently, barrier-free passages are mostly constructed using cast-in-place concrete or integral steel structure welding technology, which must be constructed simultaneously with the main structure during the architectural design phase. This type of integrated construction model makes the passages non-detachable and difficult to reuse, and cannot meet the rapid deployment requirements of temporary medical points and emergency transformation scenarios. For example, temporary shelter hospitals built during public health emergencies often delay the efficiency of patient transfer due to the long construction period of traditional passages.

[0005] (2) Poor terrain adaptability: Prefabricated passages of fixed size are difficult to adapt to complex site conditions (such as curved stairs and discontinuous height difference terrain). Customized modifications (such as cutting, welding, and concrete filling) are required, which increases costs and easily damages the structural strength after the modification.

[0006] (3) Dynamic risk control is insufficient. Existing passages generally lack active safety devices. On steep slopes or slippery environments, wheelchairs are prone to sideways slipping and losing control due to inertia or insufficient friction, which poses a serious safety hazard to electric wheelchair users. At the same time, traditional handrails only provide static support and cannot adjust the grip height in real time according to the user's movements or provide emergency braking functions, making it difficult to meet the diverse needs of users.

[0007] Based on this, the present invention proposes an assembled barrier-free passage and a construction method thereof to solve the problems existing in the above-mentioned prior art. Summary of the invention

[0049] The following will describe the prefabricated barrier-free passage of the present invention in conjunction with the Figures 1 - 11 description of the appended drawings of the specification.

[0050] Example 1:

It includes inclined passage 1, corner platform and inclined passage 2. One end of inclined passage 1 is connected to the topmost stair of the main structure of the hospital building through stair steel plate group 5, and the other end is connected to the corner platform through corner steel plate group 4. The other end of the corner platform is connected to inclined passage 2 through corner steel plate group 6. The other end of inclined passage 2 contacts the ground, forming a safe passage for people with mobility difficulties to travel; and guide rails 8 are symmetrically installed on the inner sides of the handrail groups 3 of inclined passage 1, corner platform and inclined passage 2, and dynamic fixing mechanisms 9 are arranged on the guide rails 8.

[0052] In the above description, channel frames 7 for controlling the height and position fixation of inclined passage 1, corner platform and inclined passage 2 are assembled at the bottoms of inclined passage 1, corner platform and inclined passage 2, so as to control the inclination of inclined passage 1 and inclined passage 2 during the installation process through channel frame 7, so that the inclination meets the installation requirements, and the installation and use are flexible. Inclined passage 1, corner platform and inclined passage 2 are all prefabricated structures, which are convenient for on-site assembly, and at the same time, the inclination of inclined passage 1 and inclined passage 2 during installation can be adjusted. By the cooperation of guide rail 8 and dynamic fixing mechanism 9, a dynamic fixing mechanism can be formed to dynamically fix the wheelchair during use and ensure the driving safety of the wheelchair on the barrier-free passage.

[0053] In a preferred embodiment, asFigure 1 , Figure 2 , Figure 3 , such as 4, Figure 5 , Figure 6 and Figure 7 As shown in Figure 7 , both the first inclined channel and the second inclined channel are assembled by a number of channel sections. Between two channel sections of the first inclined channel, they are connected by the corner steel plate group 4, and between two channel sections of the second inclined channel, they are connected by the corner steel plate group 6.

[0054] In the above description, through the setting of the channel sections, when in use, according to needs, multiple channel sections can be connected together by the corner steel plate group 4 and the corner steel plate group 6 to form the first inclined channel and the second inclined channel, which is convenient to select the corresponding number of channel sections for assembly according to the installation requirements during use, so as to meet the installation and use requirements of the first inclined channel and the second inclined channel.

[0055] In a preferred embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the corner platform and the channel section both include a steel frame 1 and a steel cover plate 2. The steel frames 1 are symmetrically arranged on both sides of the steel cover plate 2, and on one side where the two steel frames 1 face each other, there is a clamping platform 12. The upper surface of the clamping platform 12 is used in cooperation with the steel cover plate 2 to install the steel cover plate 2 between the two steel frames 1 through the clamping platform 12 during use and fasten it with anti-loosening bolts to form a channel bottom plate.

[0056] In the above description, the surface of the steel cover plate 2 must be anti-slip treated, such as making anti-slip strips on the surface of the steel cover plate 2 and laying a diamond abrasive epoxy coating on the slope for anti-slip to ensure the anti-slip effect of the steel cover plate 2.

[0057] Specifically, as Figure 4 , Figure 6 and Figure 7As shown, steel bars 13 are provided on the clamping platforms 12 on the opposite sides of the two steel frames 1 to enhance the overall strength of the steel frames 1 after installation. At the same time, the steel bars 13 provided on the two steel frames 1 in the same group are arranged in a staggered manner, so that the steel bars 13 can be connected in a staggered manner, facilitating the adjustment of the installation distance between the two steel frames 1 in the same group according to the installation requirements during installation. And through holes 131 are equally spaced on the steel bars 13. The through holes 131 are used in cooperation with the stiffening steel columns 14. By passing the stiffening steel columns 14 through the through holes 131 on the corresponding steel bars 13, the connection of the steel bars 13 on adjacent steel frames 1 is realized. At the same time, in order to ensure the connection effect, external threads are processed on the outer sides of the stiffening steel columns 14 for use in cooperation with the positioning nuts 15. After installation, the stiffening steel columns 14 can be fixed by installing the positioning nuts 15 on both sides of the corresponding steel bars 13 to ensure the connection effect.

[0058] In the above description, through the cooperation of the steel bars 13 and the stiffening steel columns 14, the width of the corner platform and the channel section can be adjusted during installation, facilitating installation according to the actual on-site situation, and ensuring the flexibility of the structure during installation and the applicability of the structure.

[0059] In a preferred embodiment, as Figure 4 shown, the staircase steel plate group 5 includes a pin shaft one 51 and a number of matching staircase steel plate connecting blocks 52. The pin shaft one 51 is used in cooperation with the connecting holes provided on the steel frame 1 and the staircase steel plate connecting blocks 52, for selecting the number of staircase steel plate connecting blocks 52 to be used according to the on-site installation requirements during use, and using the pin shaft one 51 to connect the staircase steel plate connecting blocks 52 with the exit staircase of the hospital building main structure. And bolt connecting holes are also provided on the staircase steel plate connecting blocks 52. During use, the staircase steel plate connecting blocks 52 are connected with the exit staircase of the hospital building main structure by passing connecting bolts through the connecting holes.

[0060] In the above description, through the setting of multiple staircase steel plate connecting blocks 52, it is convenient to adjust the number of staircase steel plate connecting blocks 52 according to the distance between the two steel frames 1 during use, with flexible use and installation; through the setting of the pin shaft one 51, it is convenient to realize the movable connection between the staircase steel plate connecting blocks 52 and the exit staircase of the hospital building main structure.

[0061] In a preferred embodiment, as Figure 4 and Figure 5 shown, the corner steel plate group 4 includes a number of connecting steel plate parts 41 that are used in cooperation with each other. The connecting steel plate parts 41 are used in cooperation with the relief grooves 16 at the ends of the steel frames 1 provided on the corner platform and the channel section of the inclined channel one. By using anti-loosening bolts to connect the connecting steel plate parts 41 with the steel cover plates 2 on the corner platform and the channel section of the inclined channel one, the connection of adjacent inclined channel one and the connection of the inclined channel one and the corner platform are realized.

[0062] In a preferred embodiment, as Figure 4 , Figure 5 and Figure 7 shown, the corner steel plate group 6 includes a plurality of corner steel plate members 61 and a second pin shaft 62. Both ends of the corner steel plate member 61 are provided with connection holes for cooperating with the connection holes provided on the steel frame 1. The second pin shaft 62 is matched with the connection holes at the corresponding positions. During use, by passing the second pin shaft 62 through the connection holes at the corresponding positions, the connection between adjacent second inclined channels and between the second inclined channel and the corner platform is achieved.

[0063] In a preferred embodiment, as Figure 1 and Figure 2 shown, connection supports are provided at the bottom of the steel frame 1 for cooperating with the channel frame 7.

[0064] The construction process of the prefabricated barrier-free passage in this embodiment includes: First, before installation, the first inclined channel, the corner platform, the second inclined channel and the channel frame 7 are assembled on the ground as required, and after assembly, the channel frame 7 is moved to both sides of the exit stairs of the hospital building main structure, and expansion screws are installed on the ground for fixing it; after fixing the channel frame 7, finally, the first inclined channel, the corner platform and the second inclined channel are hoisted and fixed in sequence according to the construction sequence.

[0065] Embodiment 2:

[0066] As Figures 1 - 11 shown, different from the above Embodiment 1, in order to ensure the travel safety of the group of people with limited mobility during use, the handrail group 3 is symmetrically arranged inside the steel frames 1 of the first inclined channel, the corner platform and the second inclined channel for providing handrail assistance during use. The handrail group 3 includes upright posts 31, upright post sleeves 32 and tie rods 33. The upright posts 31 are detachably installed on the steel frame 1. The upright post sleeves 32 are detachably sleeved outside the upright posts 31. The tie rods 33 are arranged between adjacent two upright posts 31 and are hingedly connected to the upright post sleeves 32.

[0067] In the above description, through the setting of the upright post sleeves 32, fastening can be achieved at different height positions of the upright posts 31 to realize flexible installation; the tie rods 33 are used to connect adjacent upright posts 31 to form the handrail group 3 that serves as a handrail.

[0068] In a preferred embodiment, as Figure 1 , Figure 2 and Figure 8As shown, the column 31 also cooperates with a column positioning sleeve 11 provided on the steel frame 1. The column positioning sleeve 11 is installed through the steel frame 1, which facilitates adjusting the installation height of the column 31 according to the installation requirements during use. A number of positioning holes 311 are provided on the column 31 for cooperation with the column positioning sleeve 11 and the column sleeve 32.

[0069] In this embodiment, through the structural arrangement of the above-mentioned handrail group 3, it is convenient to adjust the installation height of the column 31 according to the on-site installation requirements during use. At the same time, when installing adjacent columns 31, it can effectively ensure the flexibility of installation and the flexibility during use.

[0070] Embodiment 3:

[0071] As Figures 1 - 11 shown, different from the above embodiment, in order to ensure the use safety of wheelchairs for the group of people with mobility difficulties during use, the guide rail 8 is designed to be formed by connecting a number of mutually connected rail sections 81. A stop head 82 is also installed at the end of the rail section 81 close to the exit staircase of the hospital building main structure. Both the rail section 81 and the stop head 82 are connected to the column sleeve 32 through connecting bolts 83, and the rail section 81 and the stop head 82 are installed on one side of the column 31 through the column sleeve 32.

[0072] In a preferred embodiment, as Figure 8 and Figure 9 shown, chutes 85 are provided on the inner sides of both the rail section 81 and the stop head 82. A number of limit card slots 84 are provided on the outer walls on both the upper and lower sides of the chute 85. The limit card slots 84 cooperate with the dynamic fixing mechanism 9. During use, the dynamic fixing mechanism 9 slides along the chute 85 to realize the guiding of the dynamic fixing mechanism 9. At the same time, through the setting of the limit card slots 84, the dynamic locking of the dynamic fixing mechanism 9 is realized.

[0073] In a preferred embodiment, as Figure 10 and Figure 11 shown, the dynamic fixing mechanism 9 includes a slider 91, a dynamic locking block 92 and a wheelchair fixing member 93; the slider 91 is slidably installed in the chute 85, the dynamic locking block 92 is movably installed on the slider 91 and cooperates with the limit card slots 84; the wheelchair fixing member 93 is provided on the outside of the slider 91 and cooperates with the wheelchair.

[0074] In the above description, during use, the slider 91 is engaged in the chute 85 and slides along the length direction of the chute 85; by connecting the wheelchair fixing member 93 with the wheelchair, during the process of the slider 91 sliding in the chute 85, the dynamic locking block 92 can dynamically lock the slider 91 to ensure the safety of the wheelchair during the downward movement along this passage.

[0075] Specifically, as shown in Figure 10 and Figure 11 As shown, the slider 91 includes an integrally formed rear clamping block 911, a connecting block 913 and an outer sliding plate 912. The rear clamping block 911 is arranged at the rear end of the connecting block 913 and is slidably arranged in the chute 85. The connecting block 913 is located in the front opening of the chute 85. The dynamic locking block 92 is movably installed in the connecting block 913. The outer sliding plate 912 is arranged at the front outer end of the connecting block 913 and is connected to the wheelchair fixing member 93.

[0076] Specifically, as shown in Figure 10 and Figure 11 As shown, a movable rod 95 is also movably arranged in the inner cavity of the connecting block 913. The movable rod 95 is movably connected to the dynamic locking block 92 through a linkage rod 96. An activity plate 97 is arranged at the other end of the movable rod 95. The activity plate 97 is connected to a pulling member 94 arranged outside the connecting block 913 through a pulling rope 99. A spring 98 is arranged at the rear side of the activity plate 97.

[0077] In the above description, by manually pulling the pulling member 94, the activity plate 97 can be driven to move backward. During the backward movement of the activity plate 97, the movable rod 95 is synchronously pulled to move backward, so that the two dynamic locking blocks 92 retract and disengage from the limit card slot 84, unlocking the state, facilitating the sliding of the slider 91 in the chute 85. During this process, the spring 98 is compressed. Therefore, when the pulling member 94 is released, under the action of the spring 98 reset, the dynamic locking block 92 is reset and re-engaged into the limit card slot 84, repeating the cycle to achieve the dynamic locking function and ensure the safety of the wheelchair during the downward movement along this channel. The pulling member 94 is a spherical structure, which is convenient for grasping during use.

[0078] Specifically, as shown in Figure 10 and Figure 11 As shown, the wheelchair fixing member 93 includes a connecting chain and a hook. The connecting chain is rotatably installed outside the outer sliding plate 912. The hook is arranged at the other end of the connecting chain and is used to hang on the main brackets such as the handrail of the wheelchair. If the chain is too long, it can be selected to be wound around the wheelchair to reduce its swing amplitude to ensure the use safety of the wheelchair during the downward movement along this channel.

[0079] In this embodiment, multiple sets of the above dynamic fixing mechanisms 9 can be installed on the guide rail section 81 and the stop head 82. During use, two dynamic fixing mechanisms 9 in the same group on the left and right sides are used to connect with the wheelchair, so that the wheelchair can maintain balance during the downward movement and avoid tipping over. At the same time, the dynamic locking during the downward sliding is realized by pulling and relaxing the pulling member 94, ensuring the use safety of this barrier-free channel.

[0080] The construction method and usage process of the prefabricated barrier-free passage described in the present invention include:

[0081] Installation: First, before installation, the inclined passage 1, the corner platform, the inclined passage 2, and the passage frame 7 are assembled on the ground as required. After assembly, the passage frame 7 is moved to both sides of the exit stairs of the main structure of the hospital building, and expansion screws are installed on the ground to fix it. After the passage frame 7 is fixed, finally, the inclined passage 1, the corner platform, and the inclined passage 2 are hoisted and fixed in sequence according to the construction sequence, and then the handrail group 3 is installed;

[0082] Usage: During normal use, people with mobility impairments can move through the inclined passage 1, the corner platform, and the inclined passage 2. When the wheelchair of a group of people with mobility impairments slides down on the above-mentioned passage, first connect the dynamic fixing mechanism 9 to the wheelchair. By manually pulling the pulling member 94, the movable plate 97 can be driven to move backward. During the backward movement of the movable plate 97, the movable rod 95 is synchronously pulled backward, so that the two dynamic locking blocks 92 contract and lose the engagement with the limit card slot 84, facilitating the sliding of the slider 91 in the sliding slot 85. During this process, the spring 98 is compressed. Therefore, when the pulling member 94 is released, under the action of the spring 98 resetting, the dynamic locking block 92 is reset and re-engaged into the limit card slot 84, repeating the cycle to achieve the above-mentioned dynamic locking function and ensure the safety of the wheelchair during the downward movement along this passage.

[0083] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
